Rickettsiales is a group of small, highly pathogenic bacteria of the family Rickettsiaceae. They are obligate intracellular pathogens that infect certain cells of vertebrates, arthropods, or protozoa. These bacteria are also known as rickettsias.<br><br>They are characterized by their small size (about 0.3-0.5 micrometers in diameter) and their inability to live outside the cells of a living host. This is due to their absolute need for a living host cell for their reproduction and survival.<br><br>Examples of Rickettsiales include:<br><br> Rock mountain spotted fever (Rickettsia rickettsii)<br> Typhus (Rickettsia typhi)<br> Endemic typhus (Rickettsia prowazekii)<br> Boutonneuse fever (Rickettsia conorii)<br> Anaplasmosis (Anaplasma phagocytophilum, a former member of Rickettsiales)<br><br>These bacteria are usually transmitted to humans through bites from infected ticks, lice, or mites.
Rickettsias are a group of bacteria that cause diseases such as Rocky Mountain spotted fever, typhus, and other tick-borne illnesses in humans. They are typically transmitted through the bite of an infected tick or louse, and can also be transmitted through contact with infected animals.
